Abraham Lincoln Signed CDV as President -- John Hay Certifies Signature as Authentic on Verso

Exceptionally rare Abraham Lincoln signed carte-de-visite photograph, taken by Alexander Gardner in 1861 and signed as President. Signed ''A. Lincoln'' below the seated portrait of Lincoln. John Hay, Lincoln's private secretary, authenticates the signature upon the verso by writing, ''I certify that the President's signature is genuine / John Hay''. With ''Brady's National Portrait Gallery'' backstamp. Measures 2.5'' x 3.75''. Very good with some foxing and wear, but with a strong signature by Lincoln. With provenance from Profiles in History and with a COA from Charles Hamilton.
